[QUOTE="JayR, post: 916322, member: 27573"] When I went to work up a new load for a .260AI with the 130 Berger VLDs, my COALs were all over the place. I typically measure the chamber to get the COAL and then set my first round for about .005" jump, take that round and measure base to ogive and go off that, and measure every 5 rounds or so confirm a constant measurement. When I did that today, I had cases with as much as .015" difference. I know each bullet from the ogive to the tip will be inconsistent, but I have never experienced that much variation from round to round. I typically like less than .003" variance, is that about right? Could it be that I was loading VLDs with a regular seating stem? I load Bergers in other cartridges and love them, but I also have the VLD stem in those. Thanks for the input. [/QUOTE]
